cloudstack_client

A CloudStack API client written in Ruby.

Install the cloudstack_client gem:

$ gem install cloudstack_client

• Access to the whole CloudStack-API from Ruby
• Interactive console for playing with the CloudStack API: cloudstack_client console
• Dynamically builds API methods based on the listApis function of CloudStack
• Command names are converted to match Ruby naming conventions (i.e. ListVirtualMachines becomes list_virtual_machines)
• Accepts Ruby Hash arguments passed to commands as options (i.e. list_all: true becomes listall=true)
• Assure all required arguments are passed
• Removes unsupported arguments and arguments with nil values from commands

require "cloudstack_client"

cs = CloudstackClient::Client.new(
  "https://cloudstack.local/client/api",
  "API_KEY",
  "SECRET_KEY"
)

cs.list_virtual_machines(state: "running").each do |vm|
  puts vm["name"]
end

Load API definition file from an alternative path and set the version:

cs = CloudstackClient::Client.new(
  "https://cloudstack.local/client/api",
  "API_KEY",
  "SECRET_KEY",
  {
    api_path: "~/cloudstack",
    api_version: "4.15"
  }
)

...or load the API definition directly from a file:

cs = CloudstackClient::Client.new(
  "https://cloudstack.local/client/api",
  "API_KEY",
  "API_SECRET",
  { api_file: "~/cloudstack/4.15.json.gz" }
)

The configuration module of CloudstackClient makes it easy to load CloudStack API settings from configuration files.

require "cloudstack_client"
require "cloudstack_client/configuration"

# looks for ~/.cloudstack.yml per default
config = CloudstackClient::Configuration.load
cs = CloudstackClient::Client.new(config[:url], config[:api_key], config[:secret_key])

Configuration files support multiple environments (i.e. ~/.cloudstack.yml):

# default environment
:default: production

# production environment
production:
  :url: "https://my-cloudstack-server/client/api/"
  :api_key: "cloudstack-api-key"
  :secret_key: "cloudstack-api-secret"

# test environment
test:
  :url: "http://my-cloudstack-testserver/client/api/"
  :api_key: "cloudstack-api-key"
  :secret_key: "cloudstack-api-secret"

You can pass options as 4th argument in CloudstackClient::Client.new. All its keys are optional.

options = {
  symbolize_keys: true, # pass symbolize_names: true in JSON#parse for Cloudstack responses, default: false
  host: 'localhost', # custom host header to be used in Net::Http. May be useful when Cloudstack is set up locally via docker (i.e. Cloudstack-simulator), default: parsed from config[:url] via Net::Http
  read_timeout: 10 # timeout in seconds of a connection to the Cloudstack, default: 60
}
cs = CloudstackClient::Client.new(config[:url], config[:api_key], config[:secret_key], options)

cloudstack_client comes with an interactive console.

$ cloudstack_client console -e prod
prod >> list_virtual_machines

New API definitions can be generated using the list_apis command.

# running against a CloudStack 4.15 API endpoint:
$ cloudstack_client list_apis > data/4.15.json
$ gzip data/4.15.json
